OIL BURNER.

Application filed January 12, 1922. Serial No. 528,788.

l 10 all whom t 'may concern Be vit known that I, Jar/ins Il. SMITH, a citiaen of the United States, and resident of 'Watertowm in the county ot Middlesex and State of Massachusetts, have invented a new and Improved Oil Burner, oi which the following is a full, clear, and exact description.

My invention relates to an oil burner, and

aims to provide certain new and use'tul iinprovements in connection with a device ot this character, and more particularly a type ot burner which is capable ot utilizing kerosene, and is also adapted for household purposes.

It is a well appreciated 'tact in connection with commercial burners, that considerable difficulty has been experienced, incident to the fact that the heat ot the nozzle was so intense as to result in an excessive amount ot expansion, and ultimate distortion ot the parts, thus destroying the further usefulness of the burner.

Various attempts have been made to overcome this diiliculty but with the exception ot structures which are relatively complicated and proportionately expensiveV these attempts have for the most part, proven unsuccessful.

rllhus, it is an object of my invention to provide a nozzle or burner proper, capable ot being utilized in connection with any type of low grade volatile fuel, but particularly adapted to consume kerosene, and by means ot the construction of which the parts will not be damaged while in operation, incident to the action of heat aside from the :tact that by means ot my improved nozzle the heat will be more evenly and extensively distrib 4o uted.

A further object of this invention is the construction of a device ot the character stated which shall produce an extremely intense flame, and the parts of which shall be extremely simple so as to render the construction of the device possible at an extremely nominal ligure, aside from `the fact that the danger of imperfect operation will be reduced to a minimum.

Further objects of this invention will become apparent in the annexed specification taken in connection with the drawings, which latter illustrate one practical embodiment of the same, and in which:

Figure 1 is a side elevation ot my iinproved type of burner, and showing the same associated with a conventional type of stove.

Figure 2 is a plan view ot the nozzle or burner proper.

Figure 3 is an enlarged sectional side view ot plie essential construction of the burner, anc

Figure 4 is a transverse sectional view taken along the line 1 4 of Figure l.

Referring now more particularly to F igure 1 it will be seen that the reference numeral 5 indicates the conventional pressure tank or other suitable source of fuel supply from which, by means of a pipe 6, fuel is conducted to the generator, it being understood that, as, in the embodiment illustrated a conventional type of stove 8 is positioned, it being understood also that any desirable type of control valve 7 may be utilized to regulate this flow.

Any desired type of generator may be utilized in connection with my burner but I preferably employ a generator of the'type which includes a casing 9, one end of which is connected to the pipe 6, the opposite end providing a discharge 10, it being noted that the interior of the casing 9 may be filled with suitable material 1l in the usual manner, and may also provide screens 12.

The vaporized gases are ejected from the discharge end 10 and bridge the gap existing between this end portion and the outer end of the elbow 13 it being noted that dur ing this operation a suilicient quantity of air enters the elbow 13 to facilitate combustion. Connected to the opposite end ot the elbow is a burner proper, which in the embodiment illustrated includes a body 14 formed with a. plurality of openings or slots 15. It will be seen that the body 14 is preferably annular, and concentrically disposed within this body is a second body 16, it being noted that a perforate tube 17 is interposed between these two elements for a purpose hereinafter specified.

Now with a View of retaining the whole properly assembled, I preferably utilize a stand including a body 18 formed with an extension 19, the latter supporting the generator at a point above the burner. Also with a view of protecting the gap existing between the discharge end 10 ot the casing 9 and the outer end rof the elbow 13, I preferably positioned a plate 2O adjacent the end ot the generator so that the flames emanating from the burner or nozzle Will not bridge to the exposed gases and ignite the same.

rlhus it will be seen that the fiuid fuel is efiiciently vapoiized Within the generator, subsequent to which the same passes to the burner, it being noted thatl during this stage of the operation, the fuel receives sufficient oxygen to induce suflicient combustion. After the fuel mixture passes into the interior of the body 16 it is free to flow through the peiforations ofthe tube 17 and so into the atmosphere, yit being noted that ignition takes place at this point, Also due to the peculiar construction of the burner it Will be appreciated. that regardless of the degree of intensity of the heat, that a ratio of eX- pansion between the various tubes will not be such asto cause a distortion of the same, as is now the casel Where a single member is utilized. Further, due to the' mounting and ldisposition of the generator, it Will be found. that the latter is subjected to the fullest benefits of the heat produced, and that a most efficient vaporization is thus accomplished.

Thus all of the objects set forth lin the preamble of this specification are achieved, and it Will J be understood that numerous modifications of structure might readily be resorted to without ink the least departing from the scope of my claims; which are- 1. A burner including a pair of tubular bodies disposed one Within, and spaced from,

the other, said bodies being formed with openings, and a perforated member interposed between said bodies and having certain of its perforations in line with said openings. 2. A burner includingv a pair of bodies disposed one Within, and spaced from the other, said bodies being formed With openings, and a perforated tube interposed between said bodies and having certain of its perforations disposed in line with said openings. v

3. A burner including a body formed of three substantially concentric tubular meinbers, two of these members having registering openings, and the third member having perforations opposite such openings.

L A burner including a body formed of an outer cylindrical member, an intermediate cylindrical member inside the outer member, and an inner cylindrical member inside the intermediate member, the inner and outer members having registering openings and the intermediate member being perforated opposite said openings.

5. A burner including a body formed of three substantialy concentric tubular members, two of these members having registering openings, the third member having perforations opposite such openings, the members interfitting snugly, and strengthening means for the burner, Iincluding ring-structures encircling the outer member near opposite ends of the burner.
